Celebrity endorsements have made big news in the race for the White House, but a number of stars have decided that the heightened political awareness around the country has created the ideal atmosphere in which to tout big issues, not individuals, that are near and dear to their hearts. In conjunction with Chicago 10, the documentary about the 1968 anti-war protests at the Democratic National Convention, Natalie Portman, Julia Louis-Dreyfus, Hill Harper, Adam Goldberg and others have joined a public-service campaign that encourages people to not merely get out and vote, but to give deeper thought to how topics from education to the environment can inform the political process.

“I am voting for more accessible education for everyone, it can be done, it is up to us to make it happen,” says CSI: NY actor and Brown University graduate Hill Harper. “I’m voting to give every American a chance to get a higher education, and I don’t think it should come with such a hefty price tag.”

Julia Louis-Dreyfus mixes the serious and silly when talking about going green, while a rather intense Adam Goldberg lets loose with his vision of democratic ideals. “I am voting for more compassion and less shock and awe,” he states. “I am voting for a president who doesn’t think war is the only avenue to peace.”

You can check out the PSAs from Hill, Julia and Adam now, and then, if you’re inspired, create your own “I Am Voting For” video and enter it in takepart.com’s contest. The winning entry will be included on the Chicago 10 DVD.
